Roll bar and seatbelt

I have a 2003 Scag tiger cub, it did not come with a roll bar or seatbelt. Never thought much about it until yesterday. A guy I know had a friend of his get killed this past Monday when the mower rolled over on him and broke his neck. I havent been able to locate a place that sells them on the internet, I guess I will check with dealer in the morning.

I know on my newer Ferris suspension mowers, they cushion the bounce but they will still BOUNCE you the heck off in some big back to back ruts in someones yard, without the seatbelt you wouldn't still be on the machine. I only do not wear it on tiny lawns where your not going very fast anyway.
